How do I know if it worked?

You will know that ellaOne® has worked when your next period starts. After taking ellaOne®, most women have a normal period at the expected time. But some may have their period later or earlier than normal.1

If your period is more than 7 days late, or is unusually light or unusually heavy, or if you experience symptoms such as abdominal pain, nausea, vomiting or breast pain, or if you have any doubt about being pregnant, do a pregnancy test.1

Pregnant after ellaOne®?

It is rare that a woman becomes pregnant after taking ellaOne® for emergency contraception, but if it happens to you, or if you accidentally took ellaOne® when you were already pregnant, you are encouraged to provide us with this information.

Please report any case of pregnancy exposed to ellaOne®on: www.hra-pregnancy-registry.com, or ask your doctor to do it for you. Information is anonymous to preserve your confidentiality. Your participation is important  to gain knowledge about pregnancies exposed to ellaOne®

There is currently no known risk to you or your pregnancy if you have taken ellaOne® while you were pregnant. Your experience could benefit other women in the future.
